Glanders 3909 
ders does not float through the air, but is transmitted 
by direct contact, or by means of watering-troughs, 
feed-boxes, hitching-posts, equipment or utensils that 
have been contaminated by a diseased animal. The dis- 
charge from the nose of a glandered animal contains 
the germs in large numbers, and wherever this dis- 
charge is scattered it is liable to infect other animals. 
Perhaps the disease is sometimes transmitted by means 
of flies. 
Glanders may occur in the chronie form or the acute 
form, or it may attack the skin in the form of farcy. 
In the early stages, and especially in the chronic form, 
glanders is difficult to diagnose on account of its in- 
sidious nature. To an ordinary observer, the horse 
appears but slightly ailing, and yet he may be badly 
diseased and a dangerous source of infection. 
The symptom usually noticed first is a slight sticky 
discharge from one or both nostrils, thin and colorless. 
As it dries about one nostril, it gives the nostril 
the appearance of being smaller than the other. As 
the disease progresses, the discharge becomes thicker, 
resembling raw linseed-oil ; later, it becomes yellowish 
and often streaked with blood. The discharge is more 
profuse when the animal is exercised, or when the head 
is lowered to drink or to eat. There is a popular idea 
among horsemen that if the discharge from the horse’s 
nose sinks in water it is glanders, while if it floats it 
is not glanders; but this is not to be relied on as 
atest. Raw, ragged ulcers, with depressed centers and 
reddish edges, appear on the mucous membrane lining 
the nostrils, and especially on the septum, or partition
